Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a tape-like storage structure for storing so-called chip-shaped electronic components without lead wires, which is provided with a plurality of storage holes at predetermined intervals. The present invention relates to an automatic manufacturing device for chip-shaped electronic component assemblies that are loaded into a chip-shaped electronic component assembly.

(Conventional technology and problems) In recent years, chip-shaped multilayer capacitors, resistors, and
Electronic components such as inductance elements are widely used, but in order to automatically attach such chip-shaped electronic components to wiring boards such as printed circuit boards, conventional materials such as aluminum and plastic have been used as shown in Figure 1. A so-called magazine type storage body was used, in which a plurality of chip-shaped electronic components 2 were stacked and loaded into a cylindrical storage body 1 consisting of a cylindrical storage body 1, and both open ends of the chip-shaped electronic components 2 were sealed with plugs 3. . However, with this magazine type, there is a limit to the number of electronic components that can be stored in the storage unit 1, so there is an inconvenience in that the storage unit set in the automatic mounting machine must be replaced frequently. Since they are loaded in direct contact with each other, there are inconveniences such as the surface being damaged when loading or unloading the container. Therefore, in an attempt to eliminate the various disadvantages of this magazine system, as shown in FIG. Using a tape-shaped storage body 6 provided with storage holes 5, chip-shaped electronic components are loaded one by one into the storage holes 5 of this storage body 6, and the openings are covered with a cover sheet such as transparent tape. A so-called tape method has been proposed in which the tape is rolled up (Japanese Unexamined Patent Publication No. 55-30857, Utility Model Application No. 55-30857).
Publication No. 47771). This tape method allows you to load a considerable number of electronic components by simply using a reel with a large diameter.
Since the electronic components are also individually loaded into the storage holes one by one, there is no problem of the electronic components being damaged due to contact with each other, making it extremely useful. However, unlike the conventional magazine system, where multiple electronic components are simply stacked and loaded, they are loaded one by one into multiple independent storage holes, making the loading process extremely complicated. Therefore, although it is impossible to mass-produce it manually, there is a problem in that there is no automatic manufacturing equipment suitable for mass-production.

The present invention has been made in view of these points, and its first purpose is to quickly load electronic components one after another into the above-mentioned storage holes formed in advance in a tape-shaped storage body, and to An object of the present invention is to provide an automatic manufacturing device for an assembly of chip-shaped electronic components, which allows a cover sheet to be attached to the body surface.

The second object of the present invention is to include the step of forming storage holes in the tape member that provides the tape-like storage body as described above, the step of sequentially loading electronic components into the storage holes, and the step of pasting a cover sheet on the surface of the storage body. An object of the present invention is to provide an automatic manufacturing apparatus for a chip-shaped electronic component assembly that can perform the following steps in a series.

(Means for Solving the Problems) In order to achieve the above-mentioned first object, an automatic manufacturing device for a chip-shaped electronic component assembly according to the first invention of this application first has a concave groove provided on the top surface. , a rail for transporting a tape-shaped storage body in which a plurality of storage holes and a plurality of feed holes are provided at predetermined intervals along the groove. In relation to this rail, a press plate that prevents the tape-shaped storage body from lifting up is provided so as to cover at least a portion of the groove on the upper surface of the rail. Further, an intermittent transfer device is provided that intermittently transfers the tape-shaped storage body on the rail. In this intermittent transfer device, a plurality of pins are provided at predetermined intervals on the circumferential surface of a disk body that is arranged at the terminal end of the rail and is driven to rotate intermittently. By intermittently rotating the disc body while simultaneously engaging multiple feed holes of the tape-shaped storage body in the groove of the rail, the tape-shaped storage body is attached to the circumferential surface of the disc body. It is transferred intermittently while being placed.

Further, the chip-shaped electronic component loading device loads the chip-shaped electronic components supplied to the side portion of the rail into each storage hole of the tape-shaped storage body transferred by the above-mentioned intermittent transfer device. It is provided to be loaded when the storage body is stopped. Further, a tape-shaped cover sheet for sealing the storage hole of the tape-shaped storage body into which chip-shaped electronic components are loaded by the chip-shaped electronic component loading device is supplied to the surface of the tape-shaped storage body by the cover sheet supplying device. Ru. Then, a cover sheet pasting device is provided so as to stick the cover sheet supplied to the surface of the tape-shaped storage body by the above-mentioned cover sheet supply device to the tape-shaped storage body. The body is composed.

Furthermore, a reel for winding up such a chip-shaped electronic component assembly is provided. This reel is driven to rotate independently of the intermittent transfer device, and thereby winds up the chip-shaped electronic component assembly transferred by the intermittent transfer device. Further, a tension roller attached via a rotatable arm presses the chip-shaped electronic component assembly that is about to be wound onto the reel, and applies a constant tension between the terminal end of the intermittent transfer device and the reel. The rotation of the reel is controlled on and off according to the position of the tension roller, which moves in accordance with the variation in the length of the chip-shaped electronic component assembly present between the chip-shaped electronic components. A switch is provided, which rotates the reel when the length of the assembly reaches a predetermined value or more, and stops the reel when the length of the chip-like electronic component assembly becomes less than a predetermined length. The chip-shaped electronic component assembly is wound onto a reel while ensuring that no tension exceeding a predetermined level is applied to the chip-shaped electronic component assembly.

Simply put, the automatic manufacturing device for chip-shaped electronic component assemblies according to the second invention of this application has, in addition to the configuration of the automatic manufacturing device according to the first invention described above, a storage hole and a tape member. A perforation device for forming a feed hole, and an intermittent transfer device (hereinafter referred to as a “second intermittent transfer device”) in the first invention for intermittently transferring a tape-shaped storage body obtained by this perforation device. ) and a first intermittent transfer device separate from the first intermittent transfer device. It is characterized by the fact that it can be carried out in a timely manner. That is, the punching device punches the tape member,
A tape-shaped storage body is formed by drilling a plurality of through-holes forming a storage hole and a plurality of through-holes forming a feed hole at predetermined intervals. The first intermittent transfer device is a device that intermittently transfers the tape-shaped storage body using the through hole drilled by the above-mentioned punching device. The tape-shaped storage body transferred by the first intermittent transfer device is transferred along the rail that is also provided in the first invention.

Moreover, in this second invention, by giving slack to the tape-shaped storage body existing between the first intermittent transfer device and the second intermittent transfer device, the tape-shaped storage body is transferred by the first intermittent transfer device. It is characterized in that the second intermittent transfer device does not apply undesired tension to the tape member or tape-shaped storage body.

(Embodiment) An embodiment of the present invention will be described below in detail along with its operation with reference to the drawings.

In FIG. 3, reference numeral 10 denotes a tape member supply device, and a shaft body 1 of a support 12 provided on a mounting table 11.
A tape member 15 made of a flexible material having a predetermined thickness, such as plastic or paper, wound around a winding frame 14 is rotatably attached to a guide 16 attached to a support 16 on the mounting table 11. roller 1
7, 18, and 19. Here, the roller 18 is driven by a motor (not shown).
The roller 19 is rotated by the tension coil spring 21, and the roller 19 is drawn toward the roller 18 by the tension coil spring 21. Further, the guide 22 is attached to the support column 16 so as to rotate about a fulcrum located at a position offset from the central axis of the roller 19. Therefore, by sandwiching the tape member 15 between the rollers 18 and 19, the tape member can be pulled out from the winding frame 14. The rotational speed of this roller 18 is set so that the transport speed of the tape member 15 is faster than the transport speed by an intermittent transport device in a subsequent process, which will be described later. Tape member 1
5 will be relaxed. Therefore, the loosened tape member 15 pushes up the arc-shaped guide guide 22 rotatably provided on the support column 16 at one end so as to cover the guide roller 19. A micro switch 23 that controls the drive of the motor that rotates the roller 18 is disposed at one end of the guide 22 attached to the column 16, so that the guide is pushed up by the loosening of the tape member. 22 pushes the switch 23, thereby cutting off the power to the motor and stopping the transport of the tape member 15. Even if the transfer of the tape member 15 is stopped, the loosened tape member is transferred by the intermittent transfer device in the subsequent process.
As the slack is eliminated, the guide 22 is pulled by the tape member 15 and moves to its original position, and the motor that rotates the roller 18 is driven again. The tape member supply device 10 includes:
By repeating such operations, the tape member 1
5 can be smoothly transferred to the subsequent process.
24 is a guide roller attached to a support 26 on the mounting table 25, which guides the tape member 15 from the tape member supply device 10; 27 is a guide roller attached to an L-shaped member 28, which guides the tape member 15 from the tape member supply device 10; The member 28 is rotatably attached to the support column 29,
The roller 27 is pulled toward the roller 24 by a tension coil spring 30. Here, the rollers 24 and 27 have a switching mechanism and are configured to detect the presence or absence of the tape member 15. In other words, the rollers 24 and 27 are
Both are made of a metal body that is electrically insulated from the center shafts 31 and 32, and the rollers 24 and 2
When the tape member is present between 7 and 7, the rollers 24 and 27, which serve as switch contacts, are in an open state, but when the tape member 15 is removed, the rollers 24 and 27, which serve as switch contacts, are in a closed state.
As a result, an alarm device that prompts the replenishment of the tape member 15 is activated, or the main power source of the automatic manufacturing equipment is shut off. 33 is a punching device provided in a frame 34 having a required height, and an upper mold 38 equipped with a punch 37 is attached to a holder 36 attached to a die set 35, and the punch 37 of this upper mold A lower mold 39 having a hole of a required size is provided below.
This upper mold 38 has a manual handle 40 at its end, and is rotationally driven at a predetermined speed by the rotation of a motor 41 disposed at the bottom of the mounting table 25 via a transmission 42 and a transmission mechanism 43. It is actuated by a drive shaft 44 (only a portion of which is shown). That is, the upper mold 38 is moved up and down by the tip of a lever 45 driven by an eccentric cam (not shown) fitted to a drive shaft 44, and the rollers 24, 27 are moved onto the lower mold 39. A through hole is formed in the tape member 15 that is guided through the tape member 15 and lightly pressed by the presser plate 46. The through hole formed in this tape member 15 is a storage hole 47 into which a chip-shaped electronic component is loaded, as shown in FIG.
and the feed hole 4 provided on the side of this storage hole 47.
Since two types of 8 are provided,
The upper mold 38 and the lower mold 39 are configured to form the required holes. 5 and 6 show a side view and a bottom view of the upper mold 38, and as is clear from these figures, the punch 3
7 includes a punch 49 forming a storage hole 47 and a feed hole 4.
8, and a punch 51 having a smaller diameter and longer length than the punch 50 and used for positioning the tape member 15 during perforation. The tip of the punch 49 forming the storage hole 47 is provided with a taper such that the tape member 15 is first punched from the end side indicated by A in FIG. A groove 52 is provided in the direction along. The purpose of configuring the punch 49 in this way is to prevent burrs occurring on the cut surface of the tape member 15 and peeling of the laminated portion of paper materials that may occur when the tape member 15 is made of cardboard. In cases where the occurrence of burrs, peeling, etc. to some extent does not pose a particular problem, the punch 49 does not necessarily need to have such a configuration. The punch 50 that forms the feed hole 48 is located behind the punch 49 that forms the storage hole with respect to the traveling direction of the tape member 15 (the direction indicated by the arrow in FIG. 6), and is used for positioning. The punch 51 is provided so as to be located in front of the punch 49 with respect to the traveling direction of the tape member 15. These punches 50 and 51 both have a punching action when first punching is performed at the tip of the tape member 15, but once the feed hole 48 is formed, the punches do not perform the punching action in the subsequent punching operation. Only the punch 50 has a punching action, and the small diameter and long punch 51 is inserted into the already punched feed hole 48 to prevent unexpected movement of the tape member when punching the storage hole 47 and the feed hole 48. It will only have an effect. As a result, the storage hole 47 and the feed hole 48 are always formed at a predetermined interval on the tape member 15. In this way, the tape member 15 becomes a tape-shaped storage body 53 having a storage hole for chip-shaped electronic components. Reference numeral 54 denotes a first intermittent transfer device that intermittently transfers the tape-shaped storage body 53, which has two L-shaped feed claws 56 and 57 that are lightly pressed by a spring 55. A lever 58 is provided on the frame 34 so as to be movable only in the longitudinal direction of the storage body 53, and is driven by a cylindrical cam (not shown) fitted to the drive shaft 44. The body 53 is moved in the direction of movement, and is retreated to its original position by a tension coil spring 59 attached to the back of the intermittent transfer device and a compression coil spring 60 arranged at the front of the intermittent transfer device. In this way, the first intermittent transfer device 54 is driven in the front-rear direction by the cooperative action of the lever 58 and the springs 59, 60. 56, 57 are

3 in the direction of travel. When the intermittent transfer device 54 retreats, the feed claws 56, 57
has a tapered back surface and is rotatably attached, so it is not locked at the rear end of the storage hole 47, and the tape-shaped storage unit that is transported in the direction of travel is not locked. The body 53 is not retreated. In this way, the first intermittent transfer device 54
The tape-like storage body 53 is intermittently transported only in the longitudinal direction thereof, a new tape member 15 is supplied from the tape member supplying device 10, and the perforating device 33 continuously perforates the tape member 15. possible. More specifically, in the first intermittent transfer device 54, the two feed claws 56 and 57 satisfy a predetermined condition for the punch 49 forming the storage hole 47 of the tape-shaped storage body 53. It is set up and configured in such a position,
As a result, even if an abnormality occurs temporarily in the distance between the storage holes 47 of the tape-shaped storage body 53 due to some disturbance and an abnormality occurs in the feeding pitch, normal feeding can be restored within a short time. A storage hole 47 formed by the punch 49 after returning to the pitch

It is smaller than p. When such conditions are set, the first intermittent transfer device 54
Although the above-mentioned excellent effects can be achieved, there are cases in which no disturbance occurs, or even if a disturbance occurs, it is small, and the size of the storage hole 47 is larger than the electronic component to be stored there. The above condition does not necessarily have to be satisfied if the value is sufficiently large. Further, in such a case, it goes without saying that the number of feeding claws may be one. 61 is a rail provided with a groove in the longitudinal direction of the upper surface, and when the tape-shaped storage object 53 is transferred by the first intermittent transfer device 54, the storage object 53 is

The pins 70 and 71 are engaged with the feed holes 48 of the tape-shaped storage body 53 positioned in the grooves of the rail 66. This constitutes a second intermittent transfer device that intermittently transfers the storage object 53 along the groove in its advancing direction. Note that the tape-shaped storage body 53 existing between the first intermittent transfer device 54 and one sprocket wheel 68 constituting the second intermittent transfer device is provided with slack as shown in the figure. It is necessary to prevent tension from being applied to the tape member 15 in the first intermittent transfer device 54 by the second intermittent transfer device consisting of sprocket wheels 68 and 69. Reference numeral 72 denotes a first tape-shaped cover sheet made of a transparent thin film such as plastic, which is wound around a winding frame rotatably attached to the shaft 74 of the support 73 at the lower part of the mounting table 25, and is also wound around the guide rollers 75, 7.
6, 77, and is pulled out from the lower surface of the rail 66 to the upper surface thereof through a through hole, and is disposed on the lower surface of the tape-shaped storage body 53 excluding the feed hole 48. It is something. 78 is a roller pressed against the guide roller 75 by a tension coil spring 79;
The roller 75 constitutes a switch, which detects the presence or absence of the tape-shaped cover sheet 72 and causes a required operation. Reference numeral 80 denotes a first heating body made of a thermally conductive material such as copper, which is disposed on the lower surface of the rail 66, and is heated by a first heater 83 at the tip of an arm 82 rotatably attached to a support column 81.
A tension coil spring 84 that is fixed to the rear end of the arm 82 is provided so as to project to the upper surface of the rail 66 through a through hole provided in the rail 66. This heating body 80, as shown in FIG.

These projecting walls 85 and 86 heat the tape-shaped cover sheet 72 to slightly melt it, thereby filling the storage hole 4 of the tape-shaped storage body 53.
It is attached to both ends of 7. That is, the heating body 80 and the heater 83 constitute a cover sheet sticking device that sticks the first cover sheet 72 to the tape-shaped storage body 53. 87 is a first solenoid electromagnet attached to the mounting table 25, and an arm 89 attached to the tip of a movable core 88 is connected to the rear end of the arm 82 to which the heater 83 is attached. It is something. This electromagnet 87 is energized when the sprocket wheels 68 and 69 constituting the second intermittent transfer device stop transferring the tape-shaped storage body 53 due to, for example, the rotation of the motor 41 being stopped. As a result, the heating element 80 protruding from the upper surface of the rail 66 is depressed, thereby preventing the tape-shaped cover sheet 72 from overmelting. 90 is attached to the second stage 64, and when the tape-shaped storage body 53 is stopped, a chip-shaped electronic component is loaded into the storage hole 47 of the tape-shaped storage body 53 existing on the upper surface of the rail 66.

The chip-shaped electronic component at the tip of the vibration supply device, which will be described later, is placed on the side of the rail 66 by two arms operated by a grooved cam or a plate cam (not shown) fitted to the rail 66. A chuck portion 91, which is picked up and loaded into the storage hole of the tape-shaped storage body, connects between the tape-shaped storage body 53 on the upper surface of the rail 66 and a vibration supply device to be described later on the side of the rail 66, as shown in FIG. It is configured to make a reciprocating motion in the shape of a letter. The chuck part 91 in this embodiment has a pipe 92 connected to a vacuum source via a switching valve such as a solenoid valve at its upper end, and sucks a chip-shaped electronic component of a vibration supply device to be described later at its bottom part. The tape-shaped container is picked up by the tape-shaped container, and by releasing the suction, the tape-shaped container is loaded into the storage hole of the tape-shaped container. This chuck part 91 is of the suction type in this embodiment, as well as
It may also be of a mechanical type in which the electronic component is held between a pair of claw bodies. Furthermore, the movement of the chuck portion 91 does not necessarily have to be in the U-shape described above. The point is that the chuck part 91 holds and picks up a chip-shaped electronic component at a certain position, moves the chip-shaped electronic component to another position, and releases the holding of the electronic component at the moved position. It is fine as long as it is something. Therefore, the mechanism for moving the chuck portion 91 may have an appropriate structure depending on the movement. As shown in FIGS. 10 and 11, the above-mentioned vibration supply device that supplies chip-shaped electronic components that are arranged on the side of the rail 66 and are picked up by the chuck portion 91 of the chip-shaped electronic component loading device 90 is as shown in FIGS.

This pedestal 108 has a groove 109 large enough to accommodate a chip-shaped electronic component in its upper part, and a fall prevention wall 109' on the back side of the groove 109.
The electronic component sent into the terminal end of the linear track 97 by vibration is received in the groove 109. The purpose of providing this pedestal 108 is so that when the chuck portion 91 of the chip-shaped electronic component loading device 90 picks up the chip-shaped electronic component, the chip-shaped electronic component is stopped without being subjected to vibration. However, if the vibration of the linear track 97 is not so large, the pedestal 108 is not necessarily required. If the pedestal 108 is not provided in this way, the electronic components sent in due to vibrations will not move onto the linear track 97.
The concave groove 106 (FIG. 12) at the terminal end is closed to prevent it from falling to the outside from the terminal end, and the electronic component in the concave groove 106 can be picked up by the chuck part 91 at the terminal end. It is necessary to form a window like this. The vibration supply device for chip-shaped electronic components configured in this manner has the above-mentioned rail 66.

This winding device 128 rolls a chip-like electronic component assembly 138, which is made up of a chip-like electronic component loaded into the storage hole 47 of the tape-like storage body 53 and cover sheets 72, 112 affixed to the upper and lower surfaces, onto its reel. 132, which automatically winds up the film as follows. In other words,
When the chip-shaped electronic component assembly 138 is sequentially transferred by the pair of sprocket wheels 68 and 69 constituting the second intermittent transfer device, the chips existing between the sprocket wheel 69 and the reel 132 The length of the shaped electronic component assembly 138 becomes longer, and the tension roller 134 moves downward by its own weight and the weight 135 using the shaft 133 as a fulcrum. When the switch 136 is pressed, the motor 130 is driven by a cam integrally provided on the shaft 133, and the chip-shaped electronic component assembly 138 is wound onto the reel 132. It will be done. When the chip-shaped electronic component assembly 138 is wound onto the reel 132, the tension roller 134
The tension generated in the motor 38 causes it to move upward, and when it is moved to a predetermined position, the switch 137 is pressed by the cam and the rotation of the motor 130 is stopped. By repeating such operations, the chip-shaped electronic component assembly 1
38 is automatically wound onto the reel 132 without being cut by the tension generated during winding. Furthermore, by having such a configuration of the winding device 138, that is, a configuration in which the winding device 138 is intermittently driven independently of the first and second intermittent transfer devices, the collection of chip-shaped electronic components is removed when winding onto the reel. This makes it possible to prevent a tension exceeding a predetermined level from being applied to the body, thereby eliminating any influence on the tape-shaped storage body 53 in the second intermittent transfer device. Note that the winding device 138 is not necessarily limited to such a configuration; for example, the winding device 138 is
If you use a type of motor that rotates when the load is below a predetermined value, but automatically stops rotating when the load exceeds that value, the reel 132 can be fitted to the shaft body driven by the motor. The winding device can be constructed by simply tightening the winding device. Reference numeral 139 denotes a power distribution board provided on the mounting table 25 via a support 140, on which necessary meters, switches, timers, etc. are arranged, and each device is controlled according to a preset program. Although not described in detail earlier, the rollers 17, 19, 24, 7
5, 76, 77, 115, 116, and 134 all have guide grooves formed on their peripheral surfaces,
The tape member 15, the tape-shaped storage body 53, the first and second cover sheets 72, 112, or the chip-shaped electronic component assembly 138 are prevented from falling off the roller peripheral surface.

Although the automatic manufacturing device for chip-shaped electronic component assemblies of the present invention is configured as described above, the above-mentioned device merely discloses one embodiment of the present invention, and is limited only to the device having the above-described configuration. Needless to say, this is not something that can be done. For example, if the tape-shaped storage body 53 in which the storage hole 47 is formed is prepared in advance, the tape member supply device 10, the punching device 3,
3. The first intermittent transfer device 54 etc. can be removed. In this case, as a means for supplying the tape-shaped storage body 53, a tape-shaped storage body supplying device having a configuration similar to that of the tape member supplying device 10 may be used, and the storage hole of this tape-shaped storage body may be Instead of using a through hole as in the above embodiment, it is also possible to use a storage hole that is a bottomed hole. Also,
In the above embodiment, the first cover sheet 72 placed on the lower surface of the tape-shaped storage body 53 is supplied and attached before electronic components are loaded into the storage holes of the tape-shaped storage body 53. In such a case, it is possible to eliminate the unexpected inconvenience of a part of the cover sheet being attached to electronic components when the cover sheet is attached, but it is not always necessary to do so. do not have.
In other words, only the adhesion position of the cover sheet is placed in the downstream process of the chip-shaped electronic component loading apparatus 90, or the cover sheet supply position and the adhesion position are both placed in the downstream process of the chip-shaped electronic component loading apparatus 90. It is also possible to do so. Furthermore, the first
When the second cover sheet 72, 112 is made of a transparent thin film as in the above embodiment, a photoelectric switch is used to detect whether a chip-shaped electronic component is loaded into the storage hole of the tape-shaped storage body. Although this can easily be done, it is not impossible to use an opaque thin film. In addition, two or more chip-shaped electronic component loading devices 90 may be arranged side by side along the longitudinal direction of the tape-shaped storage body 53, or two or more chuck portions 91 of the loading device 90 may be arranged in multiple series to load chip-shaped electronic components. It is also possible to use a corresponding number of vibration supply devices, and in such a case, the capacity for loading chip-shaped electronic components into the storage hole 47 of the tape-shaped storage body 53 is increased. In addition, in this case, the sprocket wheels 68, 6
Needless to say, the feeding pitch of the tape-shaped storage bodies 53 of the second intermittent transfer device consisting of 9 must be increased by an amount commensurate with the number of loading devices 90 or the number of chuck portions 91. It goes without saying that various other modifications may be made at will without departing from the gist of the present invention.

(Effects of the Invention) According to the present invention, in common with the first and second inventions, the chip-shaped electronic component is loaded into the storage hole of the tape-shaped storage body, the storage hole is sealed with a cover sheet, and the advantage is obtained. An automatic manufacturing device for chip-shaped electronic component assemblies is obtained, which can efficiently carry out each step of winding the tape-shaped electronic component assembly onto a reel along a series of lines, and thereby, various excellent Despite its advantages, it has become possible to mass produce chip-shaped electronic component assemblies, for which manufacturing equipment suitable for mass production has not yet been realized. It will be possible to provide the body at a low cost.

Further, the chip-shaped electronic component assembly includes a tape-shaped storage body provided by a tape member made of paper or the like. Such tape-like containers tend to stretch due to excessive tension. Such elongation causes a positional shift between the storage hole and the feed hole, causing an error in loading the chip-shaped electronic component into the storage hole by the chip-shaped electronic component loading device. Further, in the subsequent automatic mounting process of chip-shaped electronic components onto a circuit board using the chip-shaped electronic component assembly, misalignment of the storage hole or feed hole may occur, resulting in a mounting error.
However, according to the present invention, the plurality of pins are simultaneously engaged with the plurality of feed holes by the rotation of the disk body itself provided in the intermittent transfer device (in the second invention, the second intermittent transfer device). Since the tape-shaped storage body is transferred in this state, the chip-shaped electronic component loading device can accurately determine the position of the chip-shaped electronic component into the storage hole into which it is to be loaded. Moreover, such highly accurate positioning with respect to the storage hole can be ensured even when the tape-shaped storage body is transported at high speed by the intermittent transport device (second intermittent transport device). In addition, the chip-shaped electronic component assembly transferred by the intermittent transfer device (second intermittent transfer device) is wound onto a reel via a tension roller, and a switch is operated in response to the position of the tension roller. Since the rotation of the reel is controlled on and off, the chip-shaped electronic component assembly can always be wound onto the reel with a constant tension. Therefore, undesired stress is not applied to the chip-shaped electronic components housed in the chip-shaped electronic component assembly. In addition, since the rotation of the reel does not affect the tape-shaped storage objects being transferred by the plurality of pins provided in the intermittent transfer device (second intermittent transfer device), this point also has the advantage of The storage hole into which the component is to be loaded can be positioned with high precision.

Furthermore, especially according to the second invention, since the punching device is also constructed on one line, the chips can be punched through a series of manufacturing processes while using a tape member in which the storage hole and the feed hole have not yet been formed. It is possible to efficiently manufacture a shaped electronic component assembly. Further, there is no need for work or space for temporarily storing a tape member, that is, a tape-shaped storage body in which storage holes and feed holes are already formed.

Further, according to the second invention, since the tape-shaped storage body existing between the first intermittent transfer device and the second intermittent transfer device has slack, the first intermittent transfer device No undesirable tension is transmitted via the tape-like storage to the intermittent transfer device of 2 or vice versa. Therefore, undesired elongation of the tape-like storage body does not occur, and in this respect, it is also possible to prevent misalignment of the storage hole and the feed hole.
